This depends on a number of factors; First, what is your desired style?
Some styles need frequent visits to the barber in order to maintain its look.

Second, it depends on how fast your hair grows in general, people that are going bald tend to have a slower growth cycle, while others need haircuts more often.
Generally speaking, our hair grows half an inch per month.
